Electrolysis-Zinc electrolysis
|
High-purity zinc is produced by means of electrolysis, using strontium carbonate to remove lead impurities.The usefulness of strontium metal is due to its chemical affinity with the lead ion, both being bivalent. The two react, yielding a poorly soluble, isomorphous pair of salts in the form of hexagonal mixed crystals. These form precipitates in the zinc sulfate electrolyte, which can subsequently be removed. The high purity of the zinc product is enhanced by the high purity and reactivity of the strontium carbonate.
